外部链接的 Office 加载项清单中不需要 AppDomains？
AppDomains not needed in Office add-in manifest for external links?
我创建了一个简单的 Office 加载项，其中的清单没有 <AppDomains> 部分。然后，我将以下 link 添加到加载项 .html 文件中：
<a href="https://www.tutorialrepublic.com">Test</a>
当我在 Office Online 或桌面 MS Word 中加载加载项并单击 link 时，加载项框架从 www.tutorialrepublic.com 加载 html。
根据此处的描述，我预计这会被阻止：https://docs.microsoft.com/en-us/office/dev/add-ins/develop/add-in-manifests?tabs=tabid-1#specify-domains-you-want-to-open-in-the-add-in-window
任何人都可以解释差异吗？我发现我也可以提交表单并将 window.location.href 设置为外部域，它们在插件 iframe 中打开，而不是像预期的那样在单独的 window 中打开。
OP 链接到的文档有误。它已被纠正。相关段落现在说：
When running in Office Online, your task pane can be navigated to any URL. However, in desktop platforms, if your add-in tries to go to
a URL in a domain other than the domain that hosts the start page (as
specified in the SourceLocation element of the manifest file), that
URL opens in a new browser window outside the add-in pane of the
Office host application.
To override this (desktop Office) behavior, specify each domain you want to open in the add-in window in the list of domains specified
in the AppDomains element of the manifest file. If the add-in tries to
go to a URL in a domain that is in the list, then it opens in the task
pane in both desktop Office and Office Online. If it tries to go to a
URL that isn't in the list, then, in desktop Office, that URL opens in
a new browser window (outside the add-in pane).
Note
This behavior applies only to the root pane of the add-in. If there is an iframe embedded in the add-in page, the iframe can be
directed to any URL regardless of whether it is listed in AppDomains,
even in desktop Office.
